Digital Camera Close-Up Image Slideshows





Besides my view camera work, I also always carry a small digital camera into the field with my current model a 7.1 megapixel Nikon 7900 Coolpix. Readily at hand small digital cameras are useful for capturing a wide range of informational images. I also use the Coolpix for capturing close-up and macro images in the natural landscape with subjects as plants, wildflowers, leaves, small animals, and rock textures. I only include my most aesthetic wildflower specimens in the slideshows. The best of these images can also be accessed via the Digital Camera Close-up Thumbnail Gallery page. In order to obtain the image desciption that displays within slideshows for specific images including file size information select this link. Selectable wildflower species Latin Name Index Table

Of course all images on this site including these in the below slide shows are under copyright.

There are six slideshows of close-up images selectable below. The first page of all slideshows has slide show control information. For instance the > key will speed up the sequence while the < key will slow it down. The default image changing rate is 12 seconds. To stop the slide shows at any time, select the Stop button at the bottom of any page including that of the control page. Otherwise the default is for the images to automatically begin sequencing. One may manually sequence through image by image by selecting at any page bottom the Stop button and then forward faster button or backward slower button. Also the field at bottom center displays the current image file name or if actuated by the down arrow, a pop up window with selections for any specific image by filename. At the end of the image slide show, sequences stops at an End page where one could re-actuate the Start button or return to this page. Location abbreviations: NP = national park, NF = national forest, NM = national monument, SP = state park, SB = state beach, SR = state reserve, CP = county park, W = wilderness, OSP = open space preserve. Images are noted if captured using in camera (flash) or Litedisc (reflector). The thumbnail sheets bring up a page showing thumbnails of all images in each category including file names. Thus they can be used to identify images quickly under each slideshow.

Information about Image Sizes for Commercial Purposes

When the Coolpix captures at maximum resolution, the resulting images are 2304 pixels high by 3072 pixels wide. Note 21 of the 337 images were taken with an earlier 4mp digital camera. For comparison, the usual XVGA Windows monitor screen is only 768 by 1024 pixels with large 21 inch computer monitors typically only providing 1200 RGB phosphor dots by 1600 dots. That would likewise limit maximum pixel display of information to no more than that 1200 by 1600 pixels. Thus a 7mp camera with complementing quality optics can produce modest sized prints with decent image quality. Although all my fine art prints on my home page index are printed at 304.8 pixels per inch which is 120 pixels per centimeter that the Lightjet printer requires, a sharp image printed at 200 ppi will still look reasonable. Thus at the full resolution of 2304 by 3072 divided by 200 ppi, such will produce a 11.52 inch by 15.36 inch image at 200 ppi. Accordingly I have processed all the below images for commercial purpose to 200 ppi print output sizes. All images have been downsized or cropped to a maximum of 14 inches on the longest side. I have attempted to size images to fit the two standard framing dimensions of 11 by 14 inch and 8 by 10 inch sizes. Thus an 11 by 14 image is 2200 by 2800 pixels and an 8 by 10 image 1600 by 2000 pixels. However because of concern for image aesthetics many images have been cropped to other dimensions. Most of these other images are at even inch dimensions, ie 8 by 11 inches, or less frequently at half inch dimensions, ie 7.5 by 10 inches. A few images have been slightly upsized, and never more than 10%, in order to fit into these dimensions. The slideshows display the processed pixel dimensions representing the maximum sizes of each of these images at the end of each line of descriptive text. For example one image shows the following:

Blue phacelia up in a cloudy sky, Anza-Borrego SP, San Diego County, 1600x2000 pixels

Thus a print of the above image would be sized at 8 by 10 inches and therefore could be framed with an over the counter consumer mat and frame. So to calculate the dimensions in any of the displayed images, divide the pixel size by 200 with the result in inches. Those images that are not sized to those two standard sizes would require using a custom frame. I would not suggest framing any of these non-standard sized images in anything but custom sizes of the indicated image sizes else the aesthetic would certainly suffer.

Size of Images in Slide Shows

The actual size of displayed images in the slide shows are of course downsized from the processed pixel dimension size shown in the slideshow description fields. Regardless of the actual full image size, all displayed images have been sized so the maximum dimensions on longest sides are 720 pixels. For instance the above example would have been downsized from 1800 by 2800 pixels to 624 by 720 pixels which 25%. allig_lizard_cr2 Likewise a 1600 by 2000 pixel image would be downsized to 576 by 720 pixels which is 36%. For example the image crop at right is part of the head of a lizard that is directly from the full sized image while the small image at left is what the same area looks like when displayed at the slide show display width of 720 pixels. The image below is that same image expanded to the size of the full image at right that shows how much detail is actually missing.
